I know it's been a while since you got a comment on Degijon, but I have to wonder after reading his bio again, and seeing an old DuckTales episode recently... Was the seaweed origin based on the seaweed seen in that one episode from DuckTales where Scrooge goes to the Bermuda Triangle to find out what's caused his ships to disappear, and he runs into a virulent seaweed that traps any ships that wander into it? Cause this being a beastie of seaweed in the mid-atlantic where the Bermuda Triangle just so happens to also be, seems highly coincidental to me.

This guy means you need to be bad to the environment or else some moss monster comes while hedorah makes you want to be good so a giant turd doesn't terrorize the city so it is just a messy catch twenty two. I guess they need to battle each other so the world can be safe once more.
